Email posture for any domain: can it receive mail, can it be spoofed? MX, SPF and DMARC.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_email_domain | Full email posture for a domain: can it receive mail, and can it be spoofed? Runs MX, SPF and DMARC lookups together and returns a plain-language verdict alongside the raw records: can_receive_mail, spoofable, and a list of specific finding Inputs: domain |
get_dmarc_record | DMARC record, policy, and whether it actually protects. Returns the DMARC TXT record at _dmarc.<domain>, its policy (none / quarantine / reject), the percentage it applies to, and whether that policy protects against spoofing. Also flags th Inputs: domain |
get_mx_records | Mail exchanger records for a domain. Returns the MX hosts in priority order and whether any exist. A domain with no MX records cannot receive mail, so sending to it will bounce. Use when you only need deliverability and not spoofing posture Inputs: domain |
get_spf_record | SPF record and how strict it is. Returns the SPF TXT record, the qualifier on its `all` mechanism (fail / softfail / neutral / pass) and what that means in practice, plus whether more than one SPF record exists — which receivers treat as an Inputs: domain |
